JAMES MOGINLEY, OF CHICAGO, ILLINOIS.

BOILER-CLEANER.

SPECIFICATION forming part of Letters Patent No. 286,724, dated October16, 1883.

' Application filed February 12, 1883. (N0 model.)

To all whom it may concern.-

Be it known that I, JAMES MOGINLEY, a

b b are opened, when there will be a constant supply to the boilerthrough one of the pipes citizen of the United States of America, residlc, and a constant circulation through the other ing at Chicago, in thecounty of Cook and State of Illinois, have invented a new and usefulImprovement in Boiler-Cleaners, of which the following is aspecification, to wit:

This invention relates to improvements in boiler-cleaners; and itconsists in certain peculiarities of construction and arrangement,substantially as will be hereinafter more fully described, and set forthin the claim.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich Figure 1 is a plan view of a boiler with my improvement attached.Fig. 2 is a side elevation of the same, and Figs. 3 and 4 are detailviews of the perforated pipes placed within the boiler.

A represents a steam-boiler of any of the ordinary and well-known forms,within which I arrange two pipes, a a, at the water-level, provided oneach side with a series of perforations, a, and connected by pipes b I),having globe-valves b b, with a cylindrical receptacle, B, located atone side of the boiler in any convenient position. In the bottom of theboiler I also arrange two perforated pipes, o 0, one of which isconnected by a pipe, 0, provided with a valve, 0*, with the receptacleB, as shown in the drawings. The other pipe 0 is connected by a pipe,(I, with a supplypipe, (1, leading to the pump, and this latter pipe isprovided with a g1obe-valvc, e, by which the supply may be out off atwill, and between this valve and the pump it is also provided with agate-valve, c. The pipe d is connected to the receptacle B by a shortsection, f, which is provided with a globe-valve, f, and also with aconnection, g, having a valve, 9, leading to the waste-pipe, h, whichconnects the receptacle B with the sewer, and which latter pipe isprovided, between the vessel B and the pipe with a valve, h. The valvesare all closed except those in the sup ply d d, and water is pumped intothe boiler until it reaches the proper height-level with the upperperforated pipes, a a. Steam is then raised and the valves in the pipesc and pipe 0, the receptacle B, and the pipes b b and a a, which willdraw off all sediment in the boiler and deposit it in the vessel B,where it may be drawn off at any time to the sewer by opening the valveh. It will be readily understood that the shutting off of the pipeleading to the pump does not in any way interfere with the circulationthroughthe other pipes and the receptacle B, and that any one of thepipes themselves may be blown off at any time without interferingwiththeaction of the othersas, for instance, the closing of the valves 6 and fand opening the valve y will enable me to blow off one of the pipes cand the pipe (1 and f to the sewer without passing through thesediment-receptacle B or interfering with the circulation through theother pipes; or the other pipe 0 may be blown off without stopping thesupply by simply shutting the valves b b and f and opening the valve hto the sewer. Again, the surface-pipes a a and their connections may beeasily blown off by closing the valve 0" and opening h. The valves f andg always remain closed except when they are opened for special work, asthe blowing off of one of the pipes, 850. It willbe seen that thisconstant circulation of water through the lower pipes, I c 0, keeps thesediment in the bottom of the boiler stirred up and draws it off, whilethe upper ones, a a, draw off all that may collect upon the surface ofthe water. As seen by Fig. 4, the lower perforated pipes, c e, havetheir perforations arranged above and below and upon each sidealternately, so that all dirt will be readily drawn off at any stage ofthe water, and the pipes not weakened by being perforated too closely.The pipes at and a have T-connection x :v with the pipes (Z and 0, sothat they can be disconnected, and the pipesa and 0 may be readilycleaned by the insertion of a rod or other means to prevent "allconstructed and arranged to operate substantially as and for the purposeset forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES MCGINLEY.
